Product Features
Fully insulated, fully sealed, maintenance-free, and reliable guarantee of personal safety;
The structure is compact, the size is only 1/3-1/5 of the European transformer of the same capacity, and the height is low;
A split-box structure can be adopted to avoid oil contamination in the transformer oil tank;
The high-voltage side adopts double fuse full-range protection, which greatly reduces costs;
It can use both ring network and terminal;
The box body is made of honeycomb double-layer composite panel, which has good heat insulation effect:
An electronic phase loss protector is installed on the low-voltage side. When abnormal voltage occurs in the system, the main switch can bequickly disconnected:
An oil-immersed load switch or SF: load switch is installed on the high-voltage side, which can be upgraded electrically,laying the foundation for realizing distribution network automation:
Use oil-immersed S11/S13 or S20/S22 series transformers with better performance
